Protocol

cell viability were quantified by Alamar Blue assay, 72 hr after initiation of BI 2536 treatment or the vehicle control. The bar chart summarizes the mean values for half-maximal growth inhibition for each cell line (EC50 values; [nM]) on a logarithmic scale.

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
